Laugh all you want, but when I looked at that picture the man's head turned and looked RIGHT AT ME. And at that very same moment, my doorbell rang. AND THERE WAS NO ONE THERE! But right there, hanging on the door, was a prosthetic hand IN THE SHAPE OF A HOOK!

1. Matter (and energy) can neither be created nor destroyed, only change form.2. Scientists agree that even if an object is destroyed, information about that object is maintained.

I believe, but cannot substantiate, that when we die, whatever makes us, us (be that an electric charge or sum of bits in particles), still lingers even if our physical presence no longer does.

However, I also personally believe that I'll keep an open mind and not discount the possibility until we can conclusively prove a negative. Hell, we can't conclusively prove the existence of dark matter and particles of gravity, but people are still hunting for them.

I'm troubled by the bacteria.Billions of them have died and all those ghosts are just clogging up the air.

This is why I haven't seen any ghosts of humans - they're being blocked by the ghosts of bacteria.
